EMD Decomposition in Hilbert-Huang Transform

This is an EMD program for decomposing IMF components. The Hilbert-Huang Transform (HHT) is a novel non-stationary signal processing technique comprising two stages: Empirical Mode Decomposition (EMD) and Hilbert spectral analysis. The implementation involves decomposing arbitrary non-stationary signals into Intrinsic Mode Functions (IMFs) with distinct characteristic scales, followed by Hilbert spectral analysis for each IMF component to construct the signal's full Hilbert spectrum.
